UNI TAEfl PATENT GORN-PLANTER.

Application filed September 18, 1915.

To all whom it may concern:

Be it known that I, JOHN H. CRAIG, a citizen of the United States,residing at Webster City, in the county of Hamilton and State of Iowa,have invented certain new and useful Improvements in Corn- Planters, ofwhich the following is a specification.

This invention relates to improvements in corn planters, generally, moreparticularly attachments therefor at the runner end of the planter.

The invention has for its object to pro vide for lightening the draftand simultaneously removingthe trash or any 0bstruction in the path ofthe planter runner or plow.

A further object is to provide for carrying out the aforesaid ends in asimple, ex-

peditious and effective manner, and with facility.

The invention therefore consists of certain instrumentalities andfeatures of construction substantially as hereinafter described anddefined by the appended claims.

In the accompanying drawing is illustrated the preferred embodiment ofmy invention, wherein it will be understood that various changes andmodifications may be made as relates to the detailed construction andarrangement of parts without departing from the scope of the claims andin which drawing- Figure 1 is a side elevation of my invention withparts broken away. Fig. 2 is an enlarged detached view of the furrowopener or shovel. Fig. 3 is an enlarged detailed view of the invention,parts being broken away, and the furrow opener or shovel shown inexcavating position in full lines and in dotted lines, and in yieldingor inoperative position.

In carrying out my invention, I provide in connection with thecorn-planter of general construction 1, having the usual runner or shoe2, a shovel or furrow opener 3, which, itself, may be of any preferredcon struction, as disclosed particularly in Fig. 3. The furrow opener orshovel 3 has breakable or yieldable connection by means of a pin,

as 4;, with the suspender or pendant 5 pivotally connected, as at 6, tothe shoe 2, at a suitable distance above the ground surface, whereby, itis apparent, with the'shovel or furrow opener in its excavatmg posltionin event of contact with an obstruction, as for Specification of LettersPatent.

instance, at 7, Fig. 3, the shovel or furrow opener will readily yieldto the dotted line position, and thus provide against the hreakage ofthe furrow opener or shovel. It is 6 obvious that, after the passage ofthe obstruction or at the obstruction, the furrow opener or shovel maybe returned to its normal or operative position. The suspender orpendant 5 may be adjusted either forwardly or backwardly to regulate theworking angle of the furrow opener or shovel 3 by means of therearwardly extending upwardly inclined brace bar 8, the upper or outerportion of which is bifurcated or slotted longitudinally, as at a, asshown more particularly in Fig. 2, forming the laterally spaced forks orside members Z2, which receive or straddle the front end of the runnerand are provided with upper and 7 5 lower series of transverseregistering apertures 0 adapted to receive the headed pins or bolts (Zarranged to engage the upper and lower edges of the runner or shoe 2 ofthe planter, as shown in Figs. 1 and 3.

The upper end of the suspender or pendant 5 is slotted or bifurcated toreceive the runner as indicated, while the lower end thereof is alsoslotted longitudinally to receive a longitudinal web or flange 0 formedon an enlar ement or shoulder f on the rear face of the 'urrow opener orshovel whereby the latter is pivotally secured at the lower end of saidweb or flange to the suspender 5. The upper end of the web or flange eis provided with an opening 9 adapted to receive the pin 4: whereby abreakable or yieldable connection is provided between the upper end ofthe furrow opener or shovel and the suspender or pendant 5, for thepurpose specified. It will be under-stood of course, that the pin is ofwood or other suitable material capable of holding the furrow opener orshovel in working position under normal conditions, but which will breakand allow the shovel to turn on its pivot to the dotted line positionindicated in Fig. 3 should the latter engage a serious obstruction.

As above stated, the corn planter generally comprises a frame 10suitably mounted upon carrying wheels 11 whose axle 12, which issuitably connected to said frame so as to turn therein, is provided witha pinion 13 of the sprocket type which drives a link belt similarlyengaging a second sprocket pinion 15 on the seed dropping shaft 16suitably journaled beneath the seed hopper 17 and so as to suitably dropthe seed con tained in the latter into the leg 18 of the shoe 2, as ineffecting the seed or cornplanting operation.

Suitable means, as at 19, is provided for the application of the draftto the planter frame 10, said frame also being equipped with the usualhandles 20 for suitably guiding the machine.

I claim 1. An attachment for corn planters comprising a furrow opener orshovel arranged in front of the runner or plow of the planter, asuspender or pendant pivoted to the planter runner and an upwardlyinclined rearwardly extending brace connected with the lower or free endof the suspender and slidably receiving the runner to adjust the furrowopener either forwardly or backwardly in the arc of a circle to vary itsworking angle and cutting depth.

2. An attachment for corn planters comprising a suspender or pendantpivoted to the front end of the runner of the planter, a furrow openeror shovel pivoted to the lower end of said suspender or pendant and anupwardly inclined brace bar having its upper end slotted longitudinallyto receive the planter runner with its lower end connected with that ofthe suspender, said brace bar comprising the principal means ofadjusting the suspender and furrow opener or shovel either forwardly orbackwardly in the arc of a circle to vary the working angle and cuttingdepth of the latter.

3. An attachment for corn planters comprising a suspender pivoted to theplanter runner, a furrow opener or shovel pivoted to the lower end ofthe suspender, and means for adjusting the lower end of said suspenderand said furrow opener or shovel, either forwardly or backwardly in thearc copies of this patent may be obtained for five cents each, byaddressing the Gommlnioner of Eaten",-

of a circle to vary the working angle and cutting depth of the latter,said means comprising an upwardly inclined rearwardly eX- tending bracebar connected at its forward or lower end with the suspender and havinga longitudinally slotted or forked upper end provided with series oftransverse coincident apertures or openings adapted to receive headedpins or apertures arranged to engage the upper and lower edges of therunner for the purpose specified.

a. An attachment for corn planters comprising a suspender pivoted at itsupper end to the front end of the runner and having a bifurcated orlongitudinally slotted lower end, a furrow opener or runner provided onits rear face with a shoulder having a longitudinal flange or web, saidshoulder adapted to fit against the front edge of the lower slottedportion of said suspender and said flange or web fitting in the slotthereof, the furrow opener or shovel being pivoted at the lower end ofits flange or web to the lower end of the suspender, a pin extendingthrough the lower slotted end of the suspender and the upper end of saidflange or web to provide a breakable or yieldable connection between thesuspender and upper end of the furrow opener, and means comprising aninclined brace bar slidably engaging the front end of the runner foradjusting the lower end of said suspender and the furrow opener, eitherforwardly or backwardly in the arc of a circle to vary the working angleand cutting depth of the latter.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JOHN H. CRAIG.
